From Reddit user SteevyT: “My brother in law did something to irritate my wife back when they were in high school.

“My wife turned off the TV, wrote ‘broken’ on a piece of paper taped to the TV, shut off the power strip, and flipped the batteries around in the remote. Took my brother in law several days to figure it out.”

From Reddit user chiefpompadour: “At my previous job, we had separate refrigerators for the different shifts. Our food was constantly constantly being stolen or messed with. One day, my buddy and I decided to make a nice cherry cheesecake… out of cooking lard. We finished it off with graham cracker crust and cut a couple of slices out of it since we knew the thief wouldn’t be brazen enough to take the first bite. We never found out who the thief was, but we never had to worry about anyone messing with our food ever again.”

From Reddit user Brunurb1: “My coworker sometimes throws out her lunch in the garbage can at my desk instead of her own, because she claims she can’t stand the smell of old ketchup that’s been sitting out for a couple hours. I’ve asked her several times to stop, but she will then just wait until I get up to go to the bathroom and do it, and hide my garbage can under my desk so she thinks I won’t see it.

“Every time she does it, I wait until she goes to the bathroom, take out the little plastic container that she had ketchup in, and put it way in the back of her bottom desk drawer. There’s 6 in there now, the oldest is over a month old. So far, she hasn’t noticed the smell. Gonna keep doing it and see how long it takes her to notice.”
